Application filed September 18, 1909.

To all whom it may 0011001 11 Be it known that 1, Russian G. VVoonwARD,a citizen of the United States, residing at lVaukegan, in the county ofLake, State of Illinois, have invented certain new and usefulImprovements in Presser-Feet, of which the following is a description,reference being had to the accompanying drawing, and to the letters andfigures of reference marked thereon.

The invention relates to new and useful improvements in presser feet forsewing machines, and has for an object to provide a presser foot whichis especially adapted to cooperate with an upper feed dog, and which isprovided with spaces within which said feed dog may operate.

A further object of the invention is to provide a presser footwhich isespecially adapted to cooperate with an upper feed dog, which foot ispivotally supported so that said foot may rock to enable the foot andthe feed dog to pass more rapidly over cross seams or the like.

In the drawings which show by way of illustration, one embodiment of theinvention; Figure 1 is a side view of my improved presser foot showingits relation to the upper feed dog. Fig. 2 is a sectional View ild lltlthrough the foot, also showing its relation to the feed dog. Fig. 3 is aview similar to Fig. 2, showing the foot as rocked when passing over across seam. Fig. a is a bottom view of the foot. Fig. 5 is a top view ofthe same. Fig. 6 is a side view showing the foot rocked and the yokebroken away to show the slot to permit adjustment of the roller. Fig. 7is a bottom plan of the end of the feed dog. I

My improved foot comprises the usual supporting shank 1, which. issecured to the lower end of the presser bar. The presser foot iscomposed of side portions 2, 9., which are connected at the forward endby across bar 3, and at the rear side by a cross plate 4:. A pin 5 issecured to the sides 2, 2' of the foot and extends through an openingformed in the shank 1, and serves as a means for pivotally connectingthe foot proper to the shank. The shank 1 is provided at the rear sidethereof, with a recess 6. A cross bar 7 extends from side to side of thefoot, and is located in the recess 6.

When the foot is in the position shown in Figs. 1 and 2, the cross bar 7engages the Specification of Letters Patent.

upper wall of the recess 6, and limits the upward movement of the rearportion of the My improved foot is also provided with a centralsupporting rib or bar 8,'which is secured to the cross bar 3, at theforward end and to the cross plate 1, at the rear end. Said supportingrib or bar 8 is provided with a needle slot 9. This rib is locatedcentrally of the foot and between the rib and the side portions 2, 2,are two parallel spaces which receive the projecting prongs or spacedmembers 10 of the upper feed dog.

The upper feed dog is practically carried. by an arm 11, and ispivotally connected thereto at 12 so that it may be swung about itspivot by means of a suitable spring 13.

As a means for limiting the upward move ment of the feed dog, I haveprovided a roller 14 which bears on the upper face of the feed dog. Saidroller 1 is provided with laterally projecting bearings 15, which extendthrough a slot 16 formed in the-side portions 2 of the foot (see Fig.6), and are j ournaled in a yoke 17.

The yoke 17 is pivoted at 18 to the side members of the presser foot.The cross plate 4:, is provided with an opening 19 which received a stopscrew 20, which stop screw is threaded into the yoke 17. The roller 14;is located slightly in front of the pivotal support 5 for the presserfoot. The upward movement of the feed dog, through the action of thespring 18, oscillates the yoke 17 about its pivot 18, until the head ofthe stop screw 20 engages the cross plate 4. This limits the upwardmovement of the roller and by adjusting the stop screw, the position ofthe roller may be varied, and in turn the reciprocating position of thefeed dog adjusted.

-When across seam passes underneath the forward end of the foot as shownin Fig. 3, said foot is tilted and as the roller 14 is forward of thepivotal support of the foot, said roller will be likewise slightlyraised, thus allowing the feed dog to lift and pass up on to the crossseam. As soon as the cross seam passes underneath the pivotal support ofthe foot, said foot will at once swing back to its normal position. Thecentral rib or bar 8 of the foot serves not only as a means for properlyholding the material at the stitching point, but said rib will alsoengage the interlocked threads which are formed when there is nomaterial in the machine, and will feed the threads, thus enabling themachine to chain off or chain between articles being stitched.

Having thus particularly described my invention, what I claim as tosecure by Letters Patent, is V l. A presser foot comprising a shank, afoot port-ion pivoted to said shank, said foot portion including spacedside members adapted to receive therebetween an upper feed dog, andmeans carried by said side members in advance of the pivot thereofadapted to engage the upper face of the feed dog and hold the same fromvertical movement relative to the presser foot portion.

2. A presser foot comprising side members, a roller located intermediatesaid side members, and a central rib spaced from said side members, andlocated centrally of the foot and beneath said roller.

3. A presser foot comprising side members, a bar at the front endthereof connecting said side members, a plate at the rear end of thefoot connecting said side members, and a rib located centrally of thefoot, and connected to said bar and said plate said rib having a needleslot formed therein and means carried by the presser foot for holdingthe upper feed dog from vertical movement relative to the presser foot,said means being disposed above the central rib of the foot.

A presser foot comprising side members, a yoke pivoted to' said sidemembers, roller carried by said yoke, and means for adjusting theposition of said yoke about its pivot.

5.21 presser foot comprising side members, a yoke pivoted to said sidemembers, 'a cross plate connecting said side members and having anopening formed therein, said yoke extending underneath said cross plateand carrying a stop screw extending up through said opening and a rollercarried by said yoke.

6. A presser foot comprising a shank, a foot portion pivoted to saidshank, a roller carried by said foot portion in advance of the pivotthereof and adapted to engage the upper face of the feed dog and holdthe same from vertical movement relative to the foot portion.

7. A presser foot comprising a shank portion, a main fabric-engagingportion pivoted to said shank portion, a roller carried by said mainportion and adapted to engage the upper face of an upper feed dog, and

new and desire 'plate and having a stop screw neans for adjusting theposition of said roller relative to said main portion.

8. A presser foot comprising a shank portion, a main portion pivoted tosaid shank portion, a roller carried by said main portion and adapted toengage the upper face of an upper feed dog, means for adjusting theposition of said roller, and means for limiting the movement of thepresser foot about its pivot.

9. A presser foot comprising a shank, a foot portion pivoted to saidshank, said foot portion including spaced side members adapted toreceive therebetween an upper feed dog and a roller carried by said sidemembers in advance of the pivot thereof and adapted to engage the upperface of the feed dog and hold the same from vertical movement relativeto the presser foot.

10. A presser foot comprising a shank portion, a main portion pivoted tosaid shank portion, a yoke pivoted to said main portion, a rollercarried by said yoke, and located in front of the pivot for said foot,said foot having a cross plate at the rear side thereof in which isformed an opening, said yoke extending underneath said cross extendingup through said opening.

11. A presser foot comprising a shank, a foot portion pivoted to saidshank, said foot portion including spaced side members adapted toreceive therebetween an upper feed dog and a roller carried by said sidemembers in advance of the pivot thereof and adapted to engage the upperface of the feed dog and hold the same from vertical movement relativeto the presser foot, and means whereby said roller may be adjusted.

12. A presser foot including in combination, side members, a supportingshank therefor, means for connecting said side members to the shank,whereby the presser foot may be tilted, a member located between theside members and movable relative thereto, for cooperating with an upperfeeding member to prevent vertical movement of said upper feeding memberrelative to the presser foot, and means for adj usting the position ofsaid movable member.

In testimony whereof I afiix my signature,
